Vacuum Pumps Deliver High Flow at Low Vacuum Levels
KNF N920 pumps exhibit a high level of gas tightness to 6 x 10-3 mbar l/s specifications and can achieve flow rates up to 21 l/m, vacuum of 1.5 mbar absolute, and maximum continuous pressure of 0.5 bar g. Flow rates additionally can be adjusted to meet the particular requirements of a process by integrating an optional potentiometer or specifying an external analog signal to alter motor speed.
The pumps are offered in three-head OEM installation models with multi-voltage power supply input. They feature a universal (90-264VAC, 50-60Hz) AC input or brush-commutated DC or brushless DC (BLDC) motor and are designed to run quietly, efficiently, and reliably over time with minimal maintenance. Pumps operate oil-free to retain the purity of the pumped medium.
